GE, Safran launch green open-rotor tech demo

摘要

GE Aviation and Safran on June 14 launched a technology demonstration and maturation program under their CFM joint venture for a family of open-rotor engines that would run on either 100 percent sustainable aviation fuel (SAF) or liquid hydrogen by the middle of the next decade. Called Rise (Revolutionary Innovation for Sustainable Engines), the development program aims for a 20 percent improvement in fuel burn and CO_2 emissions compared with today's CFM Leap family. CFM foresees ground testing on engine modules at GE and Safran facilities starting in the middle of this decade, followed by flight testing on a GE testbed "soon thereafter," according to Safran CEO Olivier Andries, who, along with GE Aviation chief executive John Slattery hosted an online briefing during which they also announced the extension of the CFM partnership until 2050.
